451 * (pic16_freeAsmop): remove the freed register from the
453 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
455 * (pic16_popGetTempRegCond): changed function prototype, now
456 function takes also a bitVector argument v which holds the current
457 set of registers that are allocated for stack access by aopForSym,
458 registers allocated in aopForSym for accessing stack symbols are not
459 any more part of the functions usedRegs field,
460 * (genCall): some times aopOp is called for a stack variable to be
461 send, aopForSym might perform the push, if this is true make sure
462 that genCall doesn't push the variable twice by testing _G.resDirect,
463 * (genFunction): changed testing for unspecified interrupt number
464 from 256 to INTNO_UNSPEC,
465 * modified selection scheme of frame pointer generation. Previously
466 if function did use local registers a frame pointer was generated,
467 now a frame pointer is generated only if function has arguments
468 (that need PLUSW2 register access), or has stack arguments, or the
469 compiler is not instructed to omit the frame pointer,
470 * (genEndFunction): before restoring local registers that were saved
471 in the function preamble, also restore the registers that *might*
472 have been allocated for stack access,
473 * (genRet): removed some old comments,
474 * (genCmp, the active (RN's) version): added a call to the
475 pic16_genCmp_special function to perform the compare with a more
476 robust and optimized way,
477 * (genInline): a feature has been added in inline code generation,
478 which allows a wildcard variable substitution when writing inline
479 assembly. Code is incomplete and experimental therefore undocumented,
480 * (genCast): changed order of aopOp for result and right to allow
481 aopForSym to directly load the result if possible,
482 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
483 perform an optimized compare on some selected special occasions,
484 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
485 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
486 generate an IVT any more,
487 * src/pic16/main.c (pic16_optionsTable): added command line option
489 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
490 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
492 * src/pic16/NOTES: Raphael Neider added in list of active developers
493 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
494 jumptable_end to prevent bug #,
495 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
496 inCond and outCond fields,
497 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
498 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
499 turn off register spilling,
500 * (packRegsForOneUse): synced with other ports' versions although it
501 is not used currently,
502 * (pic16_packRegisters): added an optimization while reading
503 structure bitfields, some registers may be saved (malloc code is
504 decreased by 80 bytes)
506 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
508 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
509 left is a bitfield, if yes, then don't optimize assignment. Perhaps
510 this can be optimized more?
512 2005-03-10 Raphael Neider <rneider AT web.de>
514 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
515 genNearPointerGet): (hopefully) fixed access to bitfields via
516 pointers (p->bitN = x; and x = p->bitN; failed)

1150 Adding support for replacing ljmps with sjmps in jumptables
1151 generated for switch statements. For now you need to set the
1152 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1153 Now 4 algorithms for mcs51 jumptable generation are used:
1154 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1155 addresses loaded pc-relative for up to 112 cases and stack-pushing
1156 target addresses loaded with offset from dptr for up to 256 cases.

1188 * added libc directory. The current version of LibC contains string
1189 functions, ctype functions and macros and some functions of the
1190 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1191 be extensively tested in the future. Standard disclaimer here.

1205 * (genCmp): experimental code for new genCmp which uses PIC18's
1206 special compare&skip instructions. Initial tests fail some times
1207 with variables grater than 1 byte in size, so new code is disabled,
1208 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1210 * (genCast): began a fix to optimize the casting of a bit to another
1211 bit, now assigning a bitfield to another bitfield will fail, sorry,

1226 * src/pic16/ralloc.c (allocReg): add preliminary support for
1227 supporting a limited set of temporary registers,
1229 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1235 (genFunction): optimize RECEIVE iCodes in reentrant functions
1237 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4237 loaded with the linker search paths (-L arguments) and the libraries
4238 to be linked with the current source (-l arguments). Changes
4239 currently will affect only the pic16 port.
4240 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4241 include path the port specific paths and port specific libraries,
4242 * gplink command now contains the $3 argument,
4243 * src/pic16/device.h,
4244 * src/pic16/device.c,: structure PIC_device is made public and
4245 renamed to PIC16_device, the same for variable Pics which is renamed

4260 Documenting changes from previous commits.
4261 * configure.in (version 1.56),
4262 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4263 when generating output files to configure the pic16 library,
4264 but now I've commented it out, since gputils aren't installed in the
4265 SF compile farm, so library won't compile
4267 * device/lib/Makefile.in (version 1.56): initially I've added in
4268 target 'all' the prerequestive 'model-pic16' so it compiled the
4269 pic16 library, but now I've commented it out for the same reasons
4271 * added targets 'model-pic16' and 'objects-pic16' to compile the
4273 * added target 'port-specific-objects-pic16' to handle the
4274 generated libraries and copy them into the build/ directory
4275 * added target 'clean-intermediate-pic16' to clean intermediate
4276 files into pic16 directory
4277 * in target 'installdirs' added line to create directory pic16 in

4522 * src/SDCCast.c (decorateType),
4523 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
4524 LEFT_OP (left shift)
4526 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4528 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4529 (default behaviour).
4531 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4533 A python script to validate compiler diagnostic messages. It can be
4534 used to verify that sdcc complains about bad c source code and
4535 gives a good location of the error.
4536 * support/valdiag/Makefile,
4537 * support/valdiag/valdiag.py,
4538 * support/valdiag/tests/*
4540 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4555 Bug reported from Jesus Calvino-Fraga
4557 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4559 * sdcc.spec: updated
4560 * device/include/Makefile.in: don't install CVS directories
4561 * device/lib/Makefile.in: added removal of CVS directories after install
4562 * doc/Makefile: fixed install, added local_icons
4563 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4564 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4565 * src/ds390/gen.c (genRightShift): fixed bug #870788

4568 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4570 PIC16 port related changes:
4571 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4572 added variable stackPos,
4574 * gen.c: genCall, assignResultValue: added support for
4575 pushing/retrieving function parameters to/from stack,
4576 genFunction,genEndFunction: setup stack frame for the
4578 genAddrOf: will be changed according to bug 863624
4580 * added files genutils.c and genutils.h which contain gen*
4581 debugged and optimised functions extracted from gen.c
4583 * glue.c: added variable 'externs' which holds extern symbols,
4584 pic16emitRegularMap: is modified to properly handle relocatable
4585 symbols under the new scheme,
4586 pic16createInterruptVect: is modified
4587 pic16printPublics: is modified to emit 'global' assembler directives,
4588 added pic16_printExterns to print extern symbols,
4589 pic16glue: initializes stack/frame pointer in the beginning of
4590 the assembly output. Temporary hack, will be corrected later,
4591 because gplink yet does not support stack and SDCC does not
4592 yet support a type of crt0.o object to create the final binary.
4594 * Removed many lines that contain 8051 legacy code.
4595 * The code is finally placed under a 'code' directive.
4596 * Added port specific options.
4598 * _process_pragma: simplified since now we do not need *special*
4599 include file to define SFR registers. But a separate header
4600 will be needed. This will be developed later.
4601 * _pic16_parseOptions: added, parses port specific options:
4602 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4603 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4604 --preplace-udata-with=
4606 * _pic16_setDefaultOptions: modified to initialize section names,
4607 but hack is temporarly out of order since it needs improvement.
4608 * _pic16_genAssemblerPreamble: configuration words are emitted by
4609 their address instead of their name. This part is incomplete and
4610 supports only the 18Fxx2 devices. Other devices will emit an error
4611 during assembly since they do not contain the same set of config
4613 * _pic16_genIVT: is modified,
4615 * pcode.c: added definitions for some hardware registers that are needed
4617 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4618 All PCI entries are updated. Now LFSR is supported.
4619 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4620 * added pic16_newpCodeOpLit2 to support instructions with
4621 two literal arguments
4622 * pic16_pCode2str: corrected code that emits assembler instructions
4623 with two literal operands and those that have an access bit modifier
4624 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4625 this fixes a bug which caused some labels to be lost, when an
4626 assembler directive was added, i.e. banksel,
4627 * pic16_FixRegisterBanking: improved logic that causes the insertion
4629 * InlineFunction: functions that are called once, are not any more
4630 inlined. This can be a port option in the future,
4632 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4634 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4635 hold the corresponding uninitialized symbols,
4636 * pic16_allocProcessorRegister: registers have explicit marked the
4638 * pic16_allocInternalRegister: registers are explicit marked as
4640 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4641 processing list, so bit registers were lost,
4644 * ralloc.h: added field 'accessBank' and original symbol operand
4645 in register definition,
4646 * removed the field isMapped from register definition,
4648 ** Several functions have been removed from various sources:
4649 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4650 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4651 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4652 pic16_assignRelocatableRegisters
4654 ** others have been introduced:
4655 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4656 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4658 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4660 * support/scripts/inc2h.pl: changed definition of BIT_AT
4661 to emit 'sbit at' instead of 'bit at'. This was a request.
4663 PIC16 port related preliminary changes:
4664 * gen.c: prefixed function popRegFromString with
4665 pic16_ and all references to it corrected
4666 * pcode.c: all pic16_pc_* hardware registers prefixed
4667 with underscore (_),
4668 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4669 * ralloc.c: newReg(): when register is REG_SFR then
4670 set address to rIdx,
4671 pic16_allocProcessorRegister(): marks register wasUsed=0
4672 pic16_writeUsedRegs(): added a call to assign processor
4673 registers via pic16_assignFixedRegisters
4675 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4677 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4678 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4679 variables in unused register banks. Also the SSEG is placed
4680 wherever there is enough space for it, and IDATA can be anywhere
4681 in internal RAM. For now compile using -Wl-Y[stack_size].
4682 The mem file is different for this option as well, since it
4683 makes no sense of talking about DSEG lenght.
4685 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4687 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4688 in certain cases, e.g. when ROM assignment, patch provided
4689 from Albert den Haan.
4691 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4930 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4932 * src/SDCCast.c (decorateType): disabled a transformation I added in
4933 revision 1.188 (access to fields of a structure at an absolute address);
4934 it breaks with bitfields, extern declarations, and gcse analysis.
4935 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4936 could be assigned through a pointer, so don't complain.
4937 * src/SDCCast.c (astErrors),
4939 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
4941 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>
4943 * src/pic16/main.c (_pic16_genIVT): fixed interrupt vector table

5693 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5694 fetching of the pointer
5695 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5696 copied from genNearPointerSet()
5697 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5698 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

5714 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5715 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5716 type for bits was changed. It resulted in bit variables becoming
5717 global, which is not permitted in PIC 14 assembly output.
5719 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

5734 A few small changes that speed up the peephole optimizer.
5738 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5740 Try to make the peephole optimizer smarter by maintaining
5741 an association between the assembly source code and the
5742 iCodes that originated them. Put this information to use
5743 with a new peephole rule condition "notVolatile" so that
5744 the rules can be aggressive yet still safe.
5749 * src/mcs51/peeph.def
5751 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5755 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5756 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5757 if the left or right operand symbols have the accuse flag set.
5759 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5761 Changed the type of the result of the ! (NOT) operator to char;
5762 previously it returned the same type as the source. This allows
5763 us to eliminate all the genFloatNot functions (all of its target
5764 implementations were very buggy) since !float can use the same
5767 * src/SDCCicode.c (ast2iCode): ! returns char

5776 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5777 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5778 during interrupts. Ensure WSAVE is located at a shared bank address.
5779 2. Fixed page selection in some places
5780 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5781 the registers name strings.
5782 4. Fixed "signed / unsigned compare" compiler warnings.
5783 5. The PIC port manages its own allocation of the general purpose
5784 registers, but makes no attempt to reuse them. As a result when
5785 compiling it soon runs out of general purpose registers. Some
5786 additional code was added to the files pcode.c and device.c to walk
5787 through the function call tree and rename the registers so that they
5797 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5798 genPlus() & genMinus() when the result is the same as left or right

5804 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5806 Made bitfield a distinct type from bit so that bitfields
5807 convert as per ANSI C and bits retain their traditional
5808 boolean style behaviour. Implemented bitfield support in
5816 * src/ds390/gen.c: bit v bitfield split
5817 * src/z80/gen.c: New support for bitfields
5818 * support/regression/tests/bitfields.c: reenabled z80,
5821 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5823 Rules 246.x, 247.x relate to bitfields, the others speed up
5824 access to xdata mapped I/O devices.
5826 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5828 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5830 Cleaned up genPackBits and genUnpackBits and added two helper
5831 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5832 for literal assignments in genPackBits (thanks to Frieder for
5838 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5840 Fixed bug #748310 (pointer to function type mishandled when the
5841 function name is omitted). Also fixed a SIGSEGV when a function
5842 attribute (reentrant, etc) is used on a non-function or on a
5843 function but misplaced before the parameter list.
5845 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5847 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5848 * support/Util/SDCCerr.h,

5870 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5872 Made the constant following the "interrupt" keyword optional. If
5873 omitted, the function will not automatically be given an entry
5874 in the interrupt vector table (similar to #pragma NOIV, but
5875 less syntacticly kludgy). The interrupt number is also now
5876 range checked. Also fixed a bug in the high order bit example

6407 messages from optionsTable when a port is not configured, added
6408 support for the PIc16 port in the ports table, when executing
6409 the compiler with no port specified on command line, a default
6410 port is selected with the new macro DEFAULT_PORT which is
6411 defined in port.h, in setDefaultOptions() linkOptions is removed
6412 from initialization assignment, since now it is a set,
6413 parseCmdLine uses setParseWithComma for linkOptions, in
6414 linkEdit() linkOptions are accessed with new function indexSet()
6415 which returns the i'th item of a set variable. See SDCCset.c, in
6416 linkEdit() when calling buildCmdLine(), added linkOptions as
6417 last argument. Now users can pass arguments to gplink via the
6418 -Wl option, main() uses pic16glue() to glue up pic16 programs

6432 gpasm complaining and test the linkage with gplink, _linkCmd and
6433 _asmCmd changed to be more gplink and gpasm friendly
6434 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6435 produced an error when parsed, peep rule 12 is added to utilize
6436 movff, but it is commented out since the pCode does not support
6437 yet a command with 2 address arguments
6439 2003-05-18 <johan AT balder>
6441 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7459 2003-01-07 <johan AT balder>
7461 * src/SDCCast.c (decorateType): fixed bug #600035
7463 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>

7474 2003-01-06 <johan AT balder>
7476 * src/SDCCicode.c: fixed array add
7478 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7479 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7480 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7482 2003-01-04 <johan AT balder>
7484 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7486 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7487 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7489 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7490 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

7496 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
7497 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7499 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7500 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7502 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7504 * in \sdcc\as\mcs51\ changed these files in order to create an
7505 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7506 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7507 following files to include the previous two files: aslink.dsp,
7508 Makefile.aslink, Makefile.bcc, and Makefile.in.
7510 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7511 .adb instead of .cdb
7513 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7515 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7516 value from option --iram-size.
7518 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7520 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7523 2002-09-18 <wiml AT hhhh.org>
7525 * SDCClrange.h: exposed setFromRange() and setToRange()
7526 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7527 packRegsForAccUse() (bug 542397)
7528 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7529 multiple times and emitting the fetch operations more than once
7530 added aopGetUsesAcc() function to allow binary operators to
7531 fetch their operands in the correct order; made genMinus() emit
7532 compact code for X = LITERAL - Y
7534 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7535 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7536 sprintf() in line 1267.
7538 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7539 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7542 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7543 Changes to aslink (All the changes are marked with 'JCF'):
7545 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7548 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7549 area BSEG. Also moves, if possible, the DATA area down into the internal
7550 ram so more space is available.
7552 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7555 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7556 not bytes. Function summary() which creates a memory usage summary
7557 file with extension .mem. Reports of overlaping stack and small stack
7558 size. If the space for the stack is less than 16 bytes aslink trows a
7561 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7562 the 8051. Option 'y' for memory summary output file.
7564 Changes to sdcc (All the changes are marked with 'JCF'):
7566 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7568 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7569 overlaying area for it (uses RegBankUsed[4]).
7571 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7572 bank zero as used by default. By default aslink locates the stack
7573 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7574 the creation of the .mem file. Delegates the allocation of data area
7575 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7576 the begining of the stack area to aslink.
7578 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7579 glue() in SDCCglue.c creates an area for it.
7581 2002-09-03 Borut Razem <borut.razem AT siol.net>
7582 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7583 sdcc/src/pic/glue.c:
7584 introduced atexit() handler for teporay files removal in case of
7585 errors, assertions, ...
7587 2002-08-29 Borut Razem <borut.razem AT siol.net>
7588 * sdcc/support/cpp2/auto-host_vc_in.h:
7589 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7590 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7591 Maybe there is a similar problem with BORLANDC? It should be checked!
7593 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7594 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7595 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7596 was not executed, and the compiler (cl) launched a warning:
7597 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7599 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7600 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7602 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7603 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7605 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7606 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7607 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7608 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7609 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7610 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7611 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7612 - added Release configuration in VS projects
7613 - review of compiler an linker options
7614 - VC .exe files are generated in bin_vc directory, not to interfere
7615 with binaries generated from other projects (cygwin, mingw, bcc ...)
7617 * sdcc/src/yacc.dsp: added
7619 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7620 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7621 and insert the version number definitions from .version
7623 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7625 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7626 added - genarate auto-host.h using auto-host_vc_in.h as template
7629 removed from CVS, generated automatically
7631 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7632 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7634 2002-08-11 Borut Razem <borut.razem AT siol.net>
7635 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7637 2002-08-10 Borut Razem <borut.razem AT siol.net>
7638 * src/SDCCmain.c (main):
7639 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7640 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7641 The consequence was that some temporary files were not removed.
7644 unification of code in functions tempfilename() and tempfile():
7645 function tempnam() is defined in Visual Studio 6.0 and .NET
7647 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7649 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7650 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7651 - removed compiler command line option /WX: Treats all warnings as errors
7652 - update a list of source files, included into the project
7654 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7655 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7656 changed project type to Generic Project so that can be correcly converted to VS.NET project
7658 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7660 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7662 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7664 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7665 added return 0 statements after assert() to make compiler happy
7667 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7668 added newline in the def file to keep MSC compiler satisfied
7670 * sdcc/src/z80/gen.c:
7671 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7672 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7673 - solved MSC error in function aopDump()
7675 * sdcc_vc.h: define PREFIX as "\\sdcc"
7677 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7678 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7680 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7681 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7682 - Rewrote the register banking algorithm.
7683 - Added pCode live-range analysis to registers (for now, only non-used and
7684 singly-used registers optimized away)
7686 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7688 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.

7715 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7717 2002-03-28 Johan Knol <johan AT balder>
7719 * src/SDCCval.c: fixed bug #532436
7721 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7723 Added "char *Processor" field to the port structure.
7726 Added -p option. Allows port dependent processor to be specified.
7729 Initialized the new field char *Processor field to NULL in all ports
7732 Compiler generated registers for interrupt context saving
7733 were not getting allocated.
7735 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7738 Fixed left shift. Will promote the left side of a left shift
7739 if a) left shifting more than size of operand or b) when assigned
7740 to something size > size of left side
7742 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7744 tons of changes. Register allocation has been
7745 rewritten. Added customization for the various PICs. Flow
7746 analysis is restructured. ...
7752 Added. device.c is a PIC port hack to accomodate variations
7755 2002-03-13 Michael Hope <michaelh AT vroom>
7757 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7759 2002-03-04 johanknol <johanknol AT manik>
7761 * /src/SDCCval.c: fixed
7763 const unsigned char arr[][2] = { { 0, 1 } };
7764 t18.c:1: error: Initializer element is not constant
7766 2002-03-04 bela <bela AT manik>
7768 * /device/include/mcs51reg.h:
7769 ds89c420 register definition update
7771 2002-03-03 <johan AT FRIJA>

7850 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7852 * sdcc/src/SDCCloop.c:
7853 Previous fix was not good. basic blocks that have "break" or "return" are
7854 not really partof a loop , but live ranges used in these blocks should
7855 be live thru the entire loop, so set partOfLoop but don't add them to
7858 2002-02-21 <johan AT FRIJA>
7860 * src/SDCCcse.c: fixed bug #514308
7862 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7865 Fixed BUG #519583. If a conditional block ended in a return/break
7866 statement inside a loop, it was not being considered part of the loop.
7868 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7870 2002-02-10 Karl Bongers <karl AT turbobit.com>
7873 Fixed up SDCDB debugger somewhat. Updated debugger/README
7874 with lots of comments and notes.
7876 * device/examples/test2.c:
7877 Fix bug, "red" variable not being initialized(compiler complained).
7879 * device/examples/Makefile, examples/test3.c:
7880 Add Makefile in device/examples folder, compiles test3.c
7881 for use as a multiple module SDCDB test case.
7883 * sim/ucsim/cmd.src/cmdset.cc:
7884 Took out debug printfs in ucsim "next" command.
7887 Karl and Johan start ucsim XA support. Most dissassembly working,
7888 about 75% emulation done(plenty of work remaining).
